 //! The `tvu` module implements the Transaction Validation Unit, a
-//! 5-stage transaction validation pipeline in software.
-//! 1. streamer
-//! - Incoming blobs are picked up from the replicate socket.
-//! 2. verifier
-//! - TODO Blobs are sent to the GPU, and while the memory is there the PoH stream is verified
-//! along with the ecdsa signature for the blob and each signature in all the transactions.  Blobs
-//! with errors are dropped, or marked for slashing.
-//! 3.a retransmit
-//! - Blobs originating from the parent (leader, at the moment, is the only parent), are retransmit to all the
-//! peers in the crdt.  Peers is everyone who is not me or the leader that has a known replicate
-//! address.
-//! 3.b window
-//! - Verified blobs are placed into a window, indexed by the counter set by the leader.sockets. This could
-//! be the PoH counter if its monotonically increasing in each blob.  Erasure coding is used to
-//! recover any missing packets, and requests are made at random to peers and parents to retransmit
-//! a missing packet.
-//! 4. accountant
-//! - Contigous blobs are sent to the accountant for processing transactions
-//! 5. validator
-//! - TODO Validation messages are sent back to the leader
+//! 3-stage transaction validation pipeline in software.
+//! 1. Fetch Stage
+//! - Incoming blobs are picked up from the replicate socket and repair socket.
+//! 2. Window Stage
+//! - Blobs are windowed until a contiguous chunk is available.  This stage also repairs and
+//! retransmits blobs that are in the queue.
+//! 3. Replicate Stage
+//! - Transactions in blobs are processed and applied to the bank.
+//! - TODO We need to verify the signatures in the blobs.
